Conteúdo: 	Chagas Disease and Leishmaniasis are neglected parasitic diseases that constitute a major public health problem. In the search for new therapeutic alternatives for such pathologies, the essential oil of the leaves of Psidium brownianum Mart ex DC was investigated egarding its chemical composition, antiparasitic, and cytotoxic effects. The chemical composition of the oil was analyzed by gas chromatography coupled to mass spectrometry (GC/MS), showing two major constituents: Isogermafurene (52.93%) and Germacrone (16.02%). In antiparasitic activity, the oil was tested against the epimastigote forms of Trypanosoma cruzi, revealing 57.05% inhibition at the highest tested concentration (1000 &#956;g/mL). In regard to antiparasitic activity against promastigote forms of Leishmania braziliensis and ishmania infantum, it obtained 92.61% and 84.16% inhibition, respectively, at the highest concentrations (1000 &#956;g/mL). As for the cytotoxic effects, it showed high cytotoxicity, with IC50 = 328.9 &#956;g/mL. The inhibitory concentration (IC50) obtained the best result for the promastigote forms of L. braziliensis (IC50 = 37.53 &#956;g/mL), as well as the selectivity index (SI = 8.76). Such results generate perspectives for new research and may contribute to more effective drug discoveries.
